The sleeper seats, the staff, and the food was truly delicious. I loved the mocktail options.

Great service. Seat was a bit small but it was fine. Food was great

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

To get to jet blue at JFK from any connecting flight you have to go through security again.

I really would like it if they provided at least some limited free wi-fi.

Nice, it was nice to have a free night's stay because our layover was over 18 hours.

Could have been better. Bag rechecking could have been eliminated. Gate location and direction need to be clearly stated.

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

The food that was served was superb!!! Awesome snacks!!! Frequent drink service!!! To me, this was shocking. I took a British Airways flight from Denver to London for the first leg of my trip and the food was horrendous. Thank you for keeping us fed and satiated on such a long flight!!!!

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

I think it was a United A380 plane. The trip from Munich to Denver was about 12 hours and the preferred economy seat I paid $75 for was very cramped. The crew was nice but I was so uncomfortable and getting up to walk around didn’t really help. My legs were swollen for 4 days afterward. I would think on such a long trip the seats would have more room. I would have gone 1st class but it was 3-4 times more expensive. I won’t fly anywhere far away again. My last experience with Lufthansa was great to Italy and back, but this time I could swear everything was United and not good.

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa

This flight went smoothly and the economy plus free upgrade worked very well.

The hot towels before the second meal was an unexpected surprise. The crew was attentive and personable, and that’s a lot on a nine hour flight. And the hot pretzels were a kind of “auf wiedersehn “ to Germany.
